If I knew how to post pictures, I could show you.
However, double click on a track and look at the wave form at the start and end points.
If the WAV is not at zero at the start or end points, the chances are that you will hear a click when you play it (either at the begining or end).
For example, you night have a guitar note that plays during a bar, and extends beyond the end of the bar. You don't want this to happen, so you set the end point right at the end of the bar, which will cut off the end of the guitar note . . . the bit you don't want to hear. But where it is cut off, you will see an abrupt termination. This is where you could hear a click.
But . . . if you are not hearing clicks, then don't worry about it.
